It's Just a Phase: Water as Solid, Liquid and Gas

Solid, liquid, and gas: they all matter. Scholars create an animation of the various states of matter, experiment with the temperature of water as it changes states, and observe carbon dioxide as it changes states. The lesson also...

Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

This easy-to-perform demonstration shows students how the water cycle, specifically the processes of condensation and evaporation, purifies Earth's water supply. Just mix up some water, dirt, and gravel in a glass bowl, place a cup in...

Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

How dirty is the water you consume? Pupils investigate a contaminated water source to determine the bacterial cell count. They participate in a discussion once results are obtained and relate this to drinking water and health safety.

Incorporate reading strategies, math, research, and the scientific method into one lesson about water conservation. After reading a story about a landlady trying to determine how many people are living in an apartment, learners develop a...

Delve into the differences among solids, liquids, and gases with this PowerPoint. It is both applicable and attractive. Large, colorful diagrams display the molecular arrangement of each state of matter and their properties are arranged...

Your physical science class learns that there are three states of matter, and that adding or removing heat can cause it to change from one state to another. By the animations, printed information, and discussion between RJ and Zoe, they...

Explore the phases of water as temperature rises. Pupils consider the idea that temperature remains constant during each phase change. An interactive exercise allows your young scientists to observe the temperature and molecular motion...

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...
